K-means clustering implementation in python

WebJan 30, 2024 · The very first step of the algorithm is to take every data point as a separate cluster. If there are N data points, the number of clusters will be N. The next step of this algorithm is to take the two closest data points or clusters and merge them to form a bigger cluster. The total number of clusters becomes N-1. WebApr 8, 2024 · K-Means Clustering is a simple and efficient clustering algorithm. The algorithm partitions the data into K clusters based on their similarity. The number of clusters K is specified by the user.
